This tumour originates in the opening of the biliary duct, invading the wall and disseminating by growing three-dimensionally, forming a nodular mass that gives rise to obstructive symptoms. Several studies have shown that patients with the intraductal papillary type have a better prognosis than ds with the scleral-nodular varieties, 21 with an average survival of 55 and 33 months, respectively, 22 while vascular and ganglion involvement are less frequent in the intraductal papillary subtype.

Palliation of irresectable hilar cholangiocarcinoma with biliary drainage and radiotherapy. Diagnosis is suspected on clinical and laboratory findings. Due to the above reasons, the utility of preoperative biliary drainage in hepatobiliopancreatic surgery has been called into question.
